Interesting. How is this implemented by the server? Just periodically refresh a cached value for each page, or are you updating the tree in real-time for all pages, and having them traverse it on each request? Either way it sounds awfully expensive for data that probably isn't used by the client most of the time. Do you have to explicitly ask for it? Is there some ad-hoc way to tell the server "hey I don't need the JSON-LD data?"
